Kncaon Application filed September-30, 1988. Serial No. 807,275.

This invention aims to provide an anchor, adapted to be driven intotheground, and so constructed that the arms of the anchor will openreadily, when the anchor is pulled up a little. 'The invention aims,moreover, to provide an anchor which will be inexpensive to manufacture,facile in operation, and void of complicated parts.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains.

With the above and other objects in ,view, which will appear .as thedescription proceeds, the invention resides in thecombination'andarrangement of parts and in thev details of constructionhereinafter described and claimed, it being understood that changes inthe precise embodiment of the invention herein disclosed, may be madewithin the scope of the invention.

In the accompanying drawings 1- Figure 1 shows in elevation, ad'eviceconstructed in accordance with the invention, parts beingbrokenaway and parts being in sections; Figure 2 is a top appears insection;

- Figure 3 is a fragmental plan showing a slight modification.

The anchor forming the subject matter of this application preferably ismade of metal throughout, and includes a body 1., A steel nut 2 isembedded-in the body 1, when the body is cast. The numeral 3' designatesa shank which is threaded into the nut 2, and because theinut 2 isprovided, the shank 3 has a very stronganchorage in the body 1. m At itsupper en'd the shank 3'1s. supplied with an eye 4.- or other. attachingelement. The lower end of the body 1 is pointed, as indicated at 5, sothat the body can be driven readily into the ground. f

The body 1 is *provided with any desired number of arms. Inthe presentembodiment of theinvention, but not of necessity, the body is suppliedwith fourarms, designated by the numeral 6. The arms 6 may plan whereinthe shank be as wide as the body 1, and at their inner ends, they areprovided, at their longitudinal or outer edges, with reenforcing flanges7.

At their outer ends, the arms 6 are curved, as shown at 8, so that whenthe arms are turned up against the body 1, as shown at 9 a 1n Figure 1,the upper ends of the arms will bear a diverging relation to each other.There are hinge knuckles 10 on the body 1, the hinge knuckles beingarranged in pairs, and one pair of hinge knuckles being located sl ghtlyabove the other pair of hinge knuckles, an observation which willbeunderstood readily when Figure 1 of the drawings is noticed. In thehinge knuckles 10, "pivot elements'll are mounted. The pivot elements 11pass through the ends of, the flanges'7 on the arms 6, the flangesextending a little beyond the inner ends of the arms.

In practical operation, the arms 6 are turned up against the sides ofthe body, as shown in Figure 1 of the drawings. By means of a suitabletool (not shown) applied to'the upper end of the body 1, and not to theshank 3 or the eye 4, the body 1 may be driven down into the ground asfar as desired. Because the pressure is applied, as aforesaid, directlyto the body 1 and not to the shank 3 or the e e 4, there is no dan er ofbreaking the shan After thebody 1 as been driven down far enough intothe ground, 'an upward pull is exerted on the eye 4 of the shank 3bymeans of block and falls, or in any other suitable way, and the body 1is pulled up a little. Because the upper ends of the arms 6 diverge, asshown at 9. the arms tend to swing downwardly, as the body 1 is pulledup, and,' ultimately, the arms 6 come to rest at right angles to thebody 1, with the inner ends of the arms 6 abutting against the body 1,as indicated by the 'numeral15. in Figure When the parts are arranged inthis position, it will be exceedingly difficult, and, indeed,practically impossible, topull the an chor out of the ground. I

In the modification shown in Figure 3 of the drawings, the arm 6a isbroadened somewhat, as at 12, near to its outer end, and is pointed atits outer end, as shown at 1.

Having thus described the invention, what is claime is:

1. In a device of the'class described, a bod of polygonal cross section,provided on eac 1 5 of its sides with outstanding hinge knucklesarranged in oppositely-disposed upper and lower pairs .plvot elementscarried by the hinge knuckles, inwardly and upwardly foldable armsmounted to swin on the pivot elements and means for limiting the outwardand downward swinging movement of the arms when the body is retracted;the knuckles of the upper pairs and the knuckles of the lower palrsbeing spaced apart both longitudinally and circumferentially of the bodywhere y eachpivot element may be mounted at each end the same length inthe lugs, the spacing of the upper and lower pairs of lugslongitudinally of the body 'ving the arms go bf the .upper pairs of knucles a separate hold onthe earth from the arms of the lower v pairs ofhinge knuckles when the body is retracted and the arms opened outwardlyand downwardly, the arms of the knuckles of the upper pairs beingdisposed out'of alignment, longitudinally of the body, with respect tothe arms of the lower pair of knuckles. N

2. A device of the class described, conao structed as set forth in claim1, and further characterized by the provision of a nut embedded in theupper end of the body, and an operating shank threaded into the nut. r
